Acts 4:13 Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marveled; and they took knowledge of them, that they had been with Jesus.
This is the reason why, when those who were called by Christ to preach, opened their mouths to speak, their listeners took knowledge that they had been with Jesus. In other words, they could speak with authority, and conviction, for they had experienced a personal, deep seated relationship with Jesus.
If and when the laymen in our day become sticklers for technicalities and information, the true word of God is buried under a maze of utterances that does not change hearts and minds, nor goads individuals to turn their lives over to the only One who would make a difference for the better.
Even Paul had to be anointed by Christ for the work of the ministry he was going to be called to, because by him coming up under the teaching, or instruction of Gamaliel, he would tend to make his preaching more information based, instead of the food for the soul as God intends.
1st Corinthians 2:4 And my speech and my preaching was not with enticing words of man's wisdom, but in demonstration of the Spirit and of power: 5 That your faith should not stand in the wisdom of men, but in the power of God.
May The Lord add His blessing to the study of His word. God bless!
